Did anyone mention "Close the door lightly when you go" by Eric Anderson? Turn around, don't whisper out my name For like a breeze, it'd stir a dying flame I'll miss someone, if it eases you to know But close the door lightly when you go

Who was the one who stole my mind Who was the one who robbed my time Who was the one who made me feel unkind So fare thee well, sweet love of mine

Also, Rosalie Sorrels wrote "Did I knock?" which has a similar theme of longing and regret, but no hostile vindictive emotions. Be gentle with yourself.
